-LRB- CNN -RRB- -- When sheriff 's deputies arrested Casey Anthony in 2008 over the death of her 2-year-old daughter , few would have anticipated it would end like this : just days after her trial , jailers arranging a clandestine release launching the Orlando woman back into a world where her story could make her rich or put her life in danger .

But that 's precisely the scenario that will play out sometime Sunday when Anthony completes serving her time on four misdemeanor counts of misleading police .

Anthony , 25 , was acquitted July 5 of murder and child neglect charges in the death of her daughter , Caylee , whose skeletal remains were found in 2008 in a wooded field . She was convicted on four counts of misleading police and was sentenced to four years in prison .

After serving nearly three years in prison while awaiting trial , she was ordered released this weekend .

The abrupt end to a criminal case that at times transfixed the nation resulted in anger and revulsion as well as donations of cash to her jailhouse account . It 's also led to speculation that the polarizing subject of the `` I Hate Casey Anthony '' Facebook page -- and the source of ire for its more than 40,000 fans -- might change her name and appearance and move someplace far away .

`` If her attorneys are doing the right thing and are doing their jobs , they 're going to have to explain to her that there is real hatred out there for her , that there have been death threats , that she can not just walk amongst the population , '' HLN legal contributor Sunny Hostin said . `` That is not just going to happen . ''

Whatever she ends up doing , first she has to get out of jail .

Few details have been publicly released about how Anthony will be let out of the Orange County Jail , where she has been held since her arrest in October 2008 .

Court officials have released limited information to reporters , mostly plans to bring three journalists inside a secure area of the jail sometime late Friday or early Saturday and cut them off from outside access while they wait for Anthony 's release .

When exactly Anthony will be freed has n't been made public .

That 's in part likely due to the intense emotions Anthony 's release has generated .

`` I know it 's bad God Forgive me but i hope someone wipes that smirk off her face . With a mack truck , '' one poster on the `` I Hate Casey Anthony '' Facebook page wrote .

Another poster , referencing rumored lucrative interview , book and movie deals , said the only thing she 'd pay to see or read would be about `` Casey Anthony 's dead body . ''

The page features Anthony 's mug shot with a bullseye target on her forehead under the headline `` Hey , Casey , I 'd watch out if I were you , just sayin ' . ''

An Oklahoma woman said she has already faced the kind of ire Anthony may face when she 's no longer behind the protective walls of the Orange County Jail .

Sammy Blackwell told CNN affiliate KOTV that a woman who mistook her for Anthony on July 8 rammed her car twice , flipping it over .

`` She said that I was trying to hurt babies , I was killing babies and she was going to stop it before it happened again , '' Blackwell told the station .

As it happens , Blackwell has a daughter named Caylee too , but that 's the end of the similarities . She says she really does n't even look that much like Anthony and worries for women who do .

Sheriff Jerry Demings said Tuesday that investigators are assessing threats to Anthony 's safety . While he said that the department was not aware of any credible threats to her life , it 's a concern that was clearly on his mind .

`` Nobody has a right to take the law in their own hands , '' he said . `` Casey Anthony had her day in court and the jury made a decision . I would hope people would step back and would not go out and commit another crime . ''

It 's also a concern for her attorneys .

`` Myself and other members of the team are concerned for her safety , very much so , '' one of her attorneys , Dorothy Sims , told HLN .

What Anthony will do after her release is unclear .

`` Well if I knew at this point I 'm sure you can appreciate that I would n't ' tell you , '' Sims said . `` I do n't believe that that has been resolved . My hope for her would be that she would be left alone and her privacy would be respected . ''

Hostin said on CNN that she 's heard reports that Anthony will go into hiding , live under an assumed name or get plastic surgery .

`` But I think we are going to hear her story because people have offered her a million dollars already for her story , '' she said .

Anthony also still has legal issues to deal with .

Her criminal team is appealing her convictions for misleading police , and she is being sued in two separate actions in civil court . One is filed by a woman with the same name Anthony gave to investigators as the name of her daughter 's nanny . The other involves a search group that wants Anthony to repay expenses they incurred looking for Caylee .

Anthony may be offered money for book and movie deals , but one offer wo n't be on the table .

Playboy founder Hugh Hefner told CNN 's Piers Morgan that the magazine wo n't be offering Anthony a pictorial .

`` I would n't reward someone like that for what has happened , '' Hefner said .

Attorney J. Cheney Mason , who once said he thought of Anthony as a granddaughter , said he does n't know what life holds in store for his client , but has hopes .

`` She is only 25 year old . A decade from now , hopefully , she 'll have some stability in her life and maybe a husband , and they can be somewhere in Montana and start over , '' he said .
